When I run my code I get the error Index in position 1 exceeds array bounds (must not exceed 61)
Error in neph_calibration_correction (line 9)
p=polyfit([nephzero(i,2) nephspan(i,2)],[0 11.15],1); %
What am I getting wrong here? I have gone through previous solutions but seems not working.
%% calculate neph slopes
load('neph_zero_span.mat');% nephzero nephspan
nephspan=nephspan([2:4 6:end],:);
spancoefs=zeros(length(nephspan),4).*nan;
for i=1:length(nephspan)
spancoefs(i,1)=nephspan(i,1);
p=polyfit([nephzero(i,2) nephspan(i,2)],[0 11.15],1); % red
spancoefs(i,2)=p(1);
p=polyfit([nephzero(i,3) nephspan(i,3)],[0 23.86],1); % green
spancoefs(i,3)=p(1);
p=polyfit([nephzero(i,4) nephspan(i,4)],[0 44.21],1); % blue
spancoefs(i,4)=p(1);
end

Ran in:
This error occurs, when you try to extract more number of elements then present in the array.
A = rand(10,1) ;
A(1) % no error
ans = 0.4508
A(7) % no error
ans = 0.7545
A(11) % error as there is no 11th element
Index exceeds the number of array elements. Index must not exceed 10.
Check the dimensions of your variables.
